STORAGE-BATTERY GRID. p

Specification of Letters Patent.

Patented Feb.- 4, 1919.

Application filed May 5, 1916. Serial No. 95,534.

To all whom it may concern:

Be it known that I, EUGENE HANDLER,

a citizen of the United States, and resi-,

grids have two sets of bars or attices which.

are held apart by ribs so that spaces for the active material are formed between.

The ribs also serve to strengthen the grid.

. Double lattice grids as described are usually formedby casting in molds, a core or draw-bar being provided "to form the spaces between the two lattices and between the ribs. When the casting has been completed it is necessary to withdraw the draw-bar,

This leaves an opening at one end of the grid which should be closed to revent'dropping out of active material w ich has been pasted into the grid. Where the ribs extend to the extremityof the grid, the portions of the grid end between the ribs have been pushed together but the ribs have prevented the complete closure-unless such a sharp bend is madeaboutthe ribs as is liable tobreak the grid.) Also if the ribs are slotted it is 'diflicultto. press the end of the grid entirely closed and the ribs are almost certain to break at the points of bending.

I overcome the diiiiculties mentioned by discontinuing the ribs short-of the edge of the grid left open by the withdrawal of the draw-bar, the lattices or bars extending beyond the ends of the ribs to the edge of the grid. The edges can then be pressed together so as to make a good closure and without danger of breakage-of the bending oarts. w

Figure 1 is a side elevation ot a grid I )odying the invention,

Fig. 2 is a fragmentary view on anenarged, scale of a portlon of the grid of Fig. 3 is a section on the line 33 of ig. 2, looking in the direction of the arow. showing the separation of the lattices beyond the end of the ribs as the grid'comes from the mold, I Fig. 4: is'av similar view showing the extended lattices bent into closing position,

Fig. 5 is a view' similar to Fig. 2 of a modified structure having rectangular instead of diamond shaped apertures, and

Fig. 6 is a section of a plate on the line as indicated at 66 of Fig. 5,

Fig. 7 is a fragmentary. section of the grid on the line 7-7 of Fig. 2.

Referring to the drawings and first ,to Figs. 1 to 4 inclusive, the grid comprises a frame 1, including the top bar 17 and the side bars 18 and 19 is substantially the thickness of the grid, from which extends the terminal pro ecti0n or lug 2. I-ntegra'lly joining the frame are vertical ribs as 3 sepa rating the two lattices one of which is -for1ned of the diagonal bars 4 crossing each other to form diamond shaped apertures as shown, while the other lattice is similarly formed of. bars as 5. .It will be observed tersection of the bars of one lattice are op-- osite the" apertures of the 'other lattice. eyond the ends of theribs 3 the lattices comprise Y shaped members 6 and 6, of substantially the same thickness as the bars of the lattice. The extended lattices termimate in marginal bars 7 and 8, of substantlally the same thickness as the bars of the lattices. Usually the frame, lattices, bars and ribs are cast integralof antimonious lead.

Fig. 3 shows clearly the extension of the lattices beyond the end 9 of a rib 3 leaving the space between the portions of the lat-- tices extending beyond. In F ig; 4 the bars 7 and 8 are shown pressed together closing the lower end of the grid, the lattice exten-. 810115 6 and 6 readily bending to permit this.

, Referring now to Figs. 5and 6, the structure is similar-to that of Figs. 1 to 4. inclu s1v e, except'that the bars forming the lat -tices, that is to say the. bars which cross the vertical ri bs, are at right angles to these ribs instead of diagonal thereto. In the lastfigures one lattice ismade up of the horizontal bars as 1?),- running at right angles to the vertical ribs 14, while the other lattice is made up of thehorizontal bars 15, the lattices being staggered so that a horizontal bar of one lattice is opposite the space betweemthe horizontal bars of the other lattice. These lattices are separated by spaces as 16 (see Fig. 6) between the ribs.

While the invention has been illustrated.

2,. An' integral castmetal, substantially rectangular, storage battery grid having a frame, two lattices, and separated ribs secured to said frame, said ribs separating said'lattices and dividing the space between them and extending substantially parallel to each other and to one dimension only of the rectangle, said lattices comprising separated bars extending from said ribs and extending beyond the ends of said ribs in the direction of said dimension, the portions of said lattices extending beyond the ends.

3. An integral cast metal, substantially rectangular, storage battery grid having a frame, two lattices, and separated ribs secured to said frame, said ribs separating said lattices and dividing the space between them and extending substantially parallel to each other and to one dimension only of the rectangle, said lattices comprising separated bars extending from said ribs and extending beyond the ends of said ribs in the direction of said dimension, each lattice having its portion which extends beyond the ends of the ribs terminating in a marginal bar.

4. An integral cast metal, substantially rectangular, storage battery grid having a frame extending partially about the grid, it being discontinued at one side thereof, a terminal or lug extending from the opposite side of said grid, vertical ribs secured to the side of said frame from which the lug extends and extending parallel to eachother and to one dimension only of the rectangle, lattices secured to said ribs in separated re-' lation, said lattices comprising separated bars extending from said ribs and extending beyond the ends of said ribs in the direction. 6 of said dimension and upon the sideof the grid opposite that to which the said terminal is secured, each of said lattices having its portion which extends beyond the ends of the ribs terminating in a marginal bar at the E. side of the grid opposite that to which said a terminal is secured.
